Embryo

When a fertilized egg has implanted in the uterus, the group of cells that will become a baby is called an embryo.

A developing, fertilized egg is known by several names within the first 2 weeks after conception, including zygote, morula (day 4), and blastocyst (day 5).

The embryonic period lasts until 8 weeks after conception (10 weeks from the last menstrual period). During this time, the embryo is forming major body structures, such as the head, spine, and internal organs. This is the time when most birth defects develop. After this point, the growing baby is called a fetus.
